previously been treated with lime, in which operation carbonic-acid gas is introduced and passed through said uices for the purpose of reakin up saccharate of lime and precipitating t e free lime contained therein. It may, however, be advantageously employed in other operations where it is desired to distribute a gaseous element throughout a body of liquid.

- Efliciency, together with convenience of construction and operation, are the prime objects of the present invention, and they are providing improved and simple means for breaking up and distributing gasbubbles throughout the liquid to be treated by preventing the clogging of conduits and apertures, by rendering the a 'paratus substantially self cleaning, and y minor arrangements which will become apparent from the description.

' By way of example an apparatus constructed in accordance with this invention is illustrated in the acco panying drawings, in which- Figure I is a side elevation and partial sec tion, and Fig. II is a plan view and section on line II II of Fig. I. I

The re'ference-lettera indicates a tank having a vertically-disposed cylindrical shell and a bottom I), shaped as an inverted cone. A large pipe 0 leads downward from the apex of the conical bottom and serves as both an inlet and an outlet for liquid and also as an inlet for gas. An outlet-valve d is connected in the pipe 0, and between the tank a and ted to the carbonation and clarifi catlon of set-root or cane uices which have A second branch I and distributer said valve a branch pipe e is led upward from pipe 0 and provided with a valve f. A

pipe 9 enters the pipe e between valve f and pipe 0, being provided with a valve 71.. Thus it is evident that the valves (1 and f being closed and valve it opened liquid sullicient amount of liquid has been admitted the valve it may be closed and the valve f opened to admit gas, which latter may then be forced under pressure through pipes e and 0 into the bottom of the tank, whereupon gaseous globules of irregular shape and volume will be formed which belch from the pipe and rise rapidly through the liquid contained in the tank.

under pressure may be forced into the tank a through the pipes g and 0. After a The bubbles or globules of gas entering the tank are too large and are not sufficiently distributed to perform eflective service in the saturation of the liquid. I have therefore provided 'novel bubble breakers and distributors which I will proceed to describe. Suspended by suitable hangers i or otherwise secured concentrically within the tank a in the.

lower part of the cylindrical section thereof is an open-bottomed annular gas receiver and distributer 7', comprising an outer cylindrical shell k, an inner cylindrical shell Z, and a rigid top m, as shown. Ran ed horizontally in the upper ends of both t c said inner and outer shells are apertures n preferably of a triangular shape with acute angles at their tops. Another circular gas receiver of a smaller diameter than the receiver is i o with and underneath the latter, projecting Well down into the conical bottom of the tank, as shown in Fig. I. The receiver p is a cylindrical shell q, having a conical top 0 and is provided with apertures r, ranged hor1-. zontally in the upper end of 1ts shell. The apertures r. are preferably triangular, but broader than the apertures n. The receiver may be held in place by any suitable means iiut I prefer to suspend it from the receiver 1 by bolts 5' or other suitable hangers, so that the conical tank-bottom b may be kept as free from obstructions as possible. A steamheating coil t may be placed in the tank a and supplied through the pipe u. A cover a may cated upon acommon axis 1 also be employed and provided with a ventilator-pipe w, through which the waste gases and vapors may escape to the outer atmosphere.

In the operation of the apparatus the liquidto be treated is forced into the tank a through the valve h and pipes g and c. The valve h is then closed, and the valve f being opened gas is forced intothe bottom of the tank a, rising through the liquid therein and collecting in the upper portion of the receiver p. When the surface of the liquid in the receiver 10 is forced down by thecollecting gas substantially to the level of the apertures 1", the gas flows out through said apertures, forming small bubbles which, being buoyant, tend to rise as soon as they become detached from the surface of the receiver. Consequently nearly all of these gas-bubbles rise at once through the liquid and are caught and col ected in the annular-shaped receiver j,

The operation is substantially repeated in the receiver j, the gas collected therein being forced out through the numerous narrow a ertures n. The apertures 12 being smaller t an the apertures 1' and the liquid in the collector not being so violently agitated as in the collector p, the bubbles issuing from the apertures n are smaller and more uniform in size than those rising into'the collector j. The collector 7' being provided with apertures n in both its inner and outer shells, the small bubbles rising therefrom are well distributed throughout the liquid and rise therethrough until absorbed or until they break u on its surface. The slo ing tops of the co lectors j and p serve to eep them free from de osits of precipitates.

The belching 0 gas into the tank through the large pipe 0 keeps the liquid constantly agitated, thus assisting in the absorption of the gas and also preventing the accumulation of precipitates upon the bottom of the tank or in the conduits. This agitation produces a complete circulation of the liquid, since there are no pockets or horizontal surfaces within the tank. The avoidance of pockets and horizontal surfacesalso renders the tank self-cleaning, since it washes itself out and em ties completely upon opening the outlet-Va ve d. I
